Subject: [PATCH V4 14/15] perf tools: Allow system-wide events to keep their own CPUs
Date: Tue, 24 May 2022 10:54:35 +0300 [thread overview]
Message-ID: <20220524075436.29144-15-adrian.hunter@intel.com> (raw)
In-Reply-To: <20220524075436.29144-1-adrian.hunter@intel.com>
Currently, user_requested_cpus supplants system-wide CPUs when the evlist
has_user_cpus. Change that so that system-wide events retain their own
CPUs and they are added to all_cpus.
